I first started by replacing the GE water valve (located @ the rear, bottom, left of the fridge). That didn't solve the issue, but didn't hurt to replace. I had plenty of water pressure coming in from the wall outlet up to the back of the filter and into the fridge; but wasn't getting any quality pressure returning down the line from there. I realized I needed to replace the MWF filter assembly. I purchased the MWF filter assembly and replaced. It's a fairly easy and staraighforward repair. There are 2 hex screws that hold the filter assembly in place. They're accessed through the front fridge door, and upper right corner. You will need the proper hex socket and an extender piece to reach it. I used my drill on the lowest setting (as to not strip the screw housings). Other than that, you just run the new assembly through the hole, line up the 2 screw holes and screw in. Then on the rear of fridge, you'll need to re-attach the new intake water line to the wall outlet & the return water line down to your water valve. Re-attach the metal protecting plate on the rear bottom of your fridge and you're done.
